“…All compartments can be affected, but anterior and superior mediastinum are the most commonly affected [1,4]. The hilum and pericardium are unusual sites [1,10]. Other unusual sites have been reported including the axilla, shoulder joint, retrocrural region, esophagus, and chest wall [1,10].…”

Mediastinal lymphangioma in adults: CT and MR imaging features

et al. 2000

View full text Add to dashboard Cite

Adult mediastinal lymphangiomas are rare lesions the diagnosis of which is difficult based on imaging studies. A retrospective study of CT, MR, and pathologic findings of mediastinal lymphangioma was performed in order to correlate pathological and imaging findings. Nine cases of adult lymphangiomas were identified in the records of our institution over a 12-year period. The CT, MR, and pathologic findings were reviewed. Lesions were classified pathologically as unilocular, cavernous, and intermediate types. Pathologic examination identified six cases of unilocular lesion, two cases of cavernous type, and one intermediate type. The CT features (n = 9) included a smoothly marginated non-enhancing mass of water attenuation (n = 7), a non-enhancing mass of soft tissue attenuation (n = 1), and an enhancing multiseptated mass (n = 1). Lesions were located in the anterior mediastinum (n = 2), right paratracheal (n = 4), subcarinal (n = 1), aortopulmonic window (n = 1) areas, and below the left hilum extending into the posterior mediastinum (n = 1). The MR features (n = 3) were characterized by an enhancing multicystic and multiseptated appearance, evocative of a cavernous type in two cases. The CT appearance of mediastinal thoracic lymphangioma is variable depending on the pathologic type. The most common unilocular type is a non-enhancing thin-walled mass on CT. A less frequent cavernous type can be suggested based on a multiseptated and loculated mass on CT and/or MR examination.

“…The hilum and pericardium are unusual sites [1,10]. Other unusual sites have been reported including the axilla, shoulder joint, retrocrural region, esophagus, and chest wall [1,10]. An evocative imaging feature is the spread of the tumor around adjacent structures without displacement or displacement of major mediastinal vessels.…”

“…Both CT and MRI are useful for the detection of mediastinal tumors. 6,10 Mediastinal lymphangiomas are sometimes shown as well-circumscribed, homogeneous, low-attenuated lesions on chest CT. Magnetic resonance imaging shows cystic components with heterogeneous signal intensity on T1-weighted images and high signal intensity on T2-weighted images.…”

Mediastinal lymphangiomyoma in an adult: Report of a case

et al. 2010

Lymphangiomyoma is a rare benign hamartoma of lymphatic origin. A 70-year-old woman presented with a 6-month history of a cough and dyspnea on exertion. Computed tomography and magnetic resonance imaging of the chest showed a 10 x 9 x 4 cm multiloculated tumor in the anterior mediastinum. We resected the tumor successfully, preserving all vital structures, even though the tumor margin was partially indistinct. The tumor was diagnosed as lymphangiomyoma based on the pathological and immunohistological findings. Hamartomatous lymphangiomyoma is not expressed by markers for secondary lymphangiomyoma of lymphangioleiomyoma, including human-melanoma-black-45 and progesterone receptor. The terminology and relevant literature on lymphangiomyoma are reviewed following this case report.

“…Cystic parts usually do not show any enhancement. Sometimes mediastinal cysts containing nonserous fluid can be mistakenly diagnosed as mediastinal solid masses with CT imaging showing high attenuation [5,6]. MRI can be used at this point to demonstrate the cystic features of these kinds of lesions.…”

Mediastinal lymphangioma is a rare, benign disease characterized by an abnormal proliferation of lymphatic vessels. Although a definitive diagnosis can be best made by surgical resection, computed tomography (CT) and magnetic resonance imaging (MRI) can be used as radiological methods to diagnose a pulmonary lymphangioma preoperatively. Endoscopic ultrasonography is a new method for visualizing pathological changes in the mediastum and may be used for preoperative diagnosis of a pulmonary lymphangioma, which is a rare example of a mediastinal disease.
